Other info. - This small species is mainly found in the lower 1/2 of Missouri. The white flowers only last for one day and are frequented by bees from the family Halictidae. Reports say that plants in a common area will all flower on the same day.
The genus and species name for the plant both mean "bearing three" because the plant typically has three flowers present at once.
